First i made a new layer that i coloured green becous i thought.. hm... I dont use much green in mah shadings. So i was looking for something different. Than i changed the opacity of the flat colour layer and put the green underneth it to give the coloura a more green look? idk! and than i put the shading to green, and shanged the option to luMI and shade, i allso did the same with the shading.

I could not make a tutorial with words on it due to i can only work in sai at the moment, withouth a proper edeting program.
